Design and Testing of Flight Control Laws on the Rascal Research Helicopter

摘要

Two unique sets of flight control laws were designed, tested and flown on the Army/NASA Rotorcraft Aircrew Systems Concepts Airborne Laboratory (RASCAL) JUH-60A Black Hawk helicopter. The first set of control laws used a simple rate feedback scheme, intended to facilitate the first flight and subsequent flight qualification of the RASCAL research flight control system. The second set of control laws comprised a more sophisticated model-following architecture. Both sets of flight control laws were developed and tested extensively using 'desktop-to-flight' modeling, analysis, and simulation tools. Flight test data matched the modelpredicted responses well, providing both evidence and confidence that future flight control development for RASCAL will be efficient and accurate. This paper describes the development and testing of two unique sets of flight control laws for the Army/NASA Rotorcraft Aircrew Systems Concepts Airborne Laboratory (RASCAL).
